Early adopters of OneUI 4.0 on Galaxy Z Flip3 and Z Fold3 report major issues

Samsung started rolling out the Just one UI 4. update to Galaxy Z Flip3 and Z Fold3 owners in South Korea a couple of times ago. Still, end users are reporting various issues with the new variation. It appears that Samsung has temporarily pulled the update when it investigates the difficulties.
Registered problems range from bricking the cellular phone or sending it into recovery mode to diminished efficiency and screen flicker. Some consumers have also noted concerns with the digicam application and that the Twin Messenger characteristic isn’t doing the job with some apps.
It is unclear when the update rollout will be resumed (or when it will be expanded to other countries). Samsung employees are talking to affected consumers to try and help them troubleshoot the issues.
